Clinton is finding huge support among women, beating Trump 60 percent to 36 percent, while men prefer Trump, but by a much smaller margin, 48-42.

The former Secretary of State and U.S. Senator also wins big with non-white voters, beating Trump 77-15. Trump takes white voters by 11 points, 52-41.

"We are starting to hear the faint rumblings of a Hillary Clinton landslide as her 10-point lead is further proof that Donald Trump is in a downward spiral as the clock ticks," Tim Malloy, assistant director of the Quinnipiac University Poll, says in the company's release detail.
